description Polyesters such as poly(ethylene terephthalate) (PET) are widely used in bottles and containers which are used for carbonated beverages, fruit juices, and certain foods. Useful polyesters have high inherent viscosities (I.V.) which allow the polyester to be formed into a parison and subsequently molded into a container. Because of the limited barrier properties with regard to oxygen, carbon dioxide and the like, PET containers are not generally used for products requiring long shelf life. For example, oxygen transmission into PET bottles that contain beer, wine and certain food products cause these products to spoil. The present invention relates to a polyester-platelet particle composite comprising at least one polyester having dispersed therein a platelet particle dispersion comprising chalcogen or platelet particles and at least one water dissipatible polymer.
